Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] see figure 1 , the present invention provides a name recognition method based on dictionaries and semantic disambiguation, including name extraction and name disambiguation, wherein,

[0033] The name extraction step is: using a name dictionary and a word segmentation dictionary to perform word segmentation and name extraction on the input text to obtain an initial name and a set of word segmentation;

[0034] The name disambiguation step is: for the set of initial name and participle, establish an adjacency matrix by the minimum gap, utilize the Floyd algorithm to calculate the shortest...

Abstract

The invention discloses a dictionary and semantic disambiguation-based name recognition method and device. The method comprises the steps of name extraction and name disambiguation. The device comprises a name extraction module and a name disambiguation module. According to the name recognition method provided by the invention, all the possible names are found out according to a name dictionary, name disambiguation is carried out through a minimum clearance and a shortest word segmentation length, and finally correct name information is obtained, so that the problems that the names cannot be distinguished and the names are excessively recognized as the word segmentation is incorrect are avoided, the Chinese semantic recognition correctness is improved and the work efficiency of related application personnel is improved.

Description

technical field [0001] The invention relates to the technical field of natural language processing applications, in particular to a name recognition method and device based on dictionaries and semantic disambiguation. Background technique [0002] With the rapid development of the Internet and big data technology, Chinese information processing technology has penetrated into related applications in various industries. Chinese names account for a relatively high proportion of unregistered words, so the word segmentation cannot be distinguished, which will lead to a low recognition accuracy rate of unregistered words. On the other hand, the recognition of Chinese names plays a very important role in the process of Chinese text mining and semantic understanding, because characters are the basis of many semantic facts or relationships. [0003] Based on this, a name recognition method and device based on dictionaries and semantic disambiguation, which can improve the accuracy o...
